The spatial distribution of total heat emissions for the five components.

Monthly Profile

The average heat emission from building surfaces remain the largest across most months of the year except for January and December. Surface heat emission peaks in May, while HVAC rejection heat emission peaks in July. Heat emission from exfiltration do not exhibit much seasonality and remain pretty steady across all months while there are some dips in the summer months for the average zong exhaust air heat loss and the HVAC relief air heat loss.
